• w > 17.5

A climber is climbing a mountain to a minimum height of 8.75 miles. - The climber has already climbed 1.3 miles. - He climbs at a rate of 2.5 miles per hour. Part A: Enter an inequality where x is the time in hours, to represent the situation. Part B: What is the minimum amount of time, in hours, it will take the climber to reach an elevation of at least 8.75 miles? Round to the nearest hour.

• A) x ≥ 3.5, Minimum time: 4 hours

• B) x ≥ 2.98, Minimum time: 3 hours

• C) x ≥ 6.73, Minimum time: 6 hours

• D) x ≥ 2.7, Minimum time: 3 hours

The length of a rectangular backyard is (a)   more than the width. The entire yard has a fence around it. No more than (b)   of fence is needed to go around the entire perimeter. A student says that x could be (c)   . Explain if this answer is reasonable or not. Circle an option to complete each sentence. (d)   [is/ is not] reasonable, because the total fencing would be [more than/less than] (e)   .

• 2w + 5 ≤ 90

• 2(w + 5) ≤ 90

• 2w + 10 ≤ 90

• 2(w + 5) + 2w ≤ 90
